I am using a programming module for an attiny85 microchip connected to a USB on my laptop. I am using the arduino IDE to program the chip.
My sketch is posted below. I cannot get the low batt warning sequence of 15 blinks at the end to run no matter what I do. All other light behaviors are executing perfectly.
What the heck am I missing???? Please help. Thx
